A healthy heart at 50 could lower dementia risk
20 August 2019
A new Whitehall II paper has found that good cardiovascular health at age 50 is associated with a lower risk of dementia onset later in life.
Researchers looked at the heart health of study participants at age 50 based on the American Heart Association's Life Simple 7 cardiovascular health score. This score is the sum of four behavioural (smoking, diet, physical activity, body mass index) and three biological (fasting glucose, blood cholesterol, blood pressure) metrics, each of them being categorized as poor (score=0), intermediate (score=1), and optimal (score=2). Researchers then looked at the association between this score and the incidence of dementia over a 25 year follow-up period. Analyses showed that those with a higher Life’s Simple 7 score were less likely to have developed dementia.
Dr Severine Sabia, lead author on the paper, said: “Our findings suggest that the promotion of healthy lifestyle and good levels of biological cardiovascular risk factors in midlife might be important for preventing dementia”
The paper has been published in The BMJ.
